Does anyone around here is knowledgeable about the original F1 Seven mod? Although I regard it as an absolute unsurpassed master piece in terms of graphical detail (where else you can find the 70-5 seasons with all cars and liveries?) I always found the physics to be way, way out.
Compared to the GPL 69 cars per instance, or even the rfactor 79's (which had ground effect for Christ's sake!), the F1 Seven cars are just glued to the track and understeer like pigs.

Although I'm no physics expert I'm looking to at least compile a list of things that are wrong and can be changed for future reference. I know it's an old game but the mod was not wholly converted to rfactor and what was did not seem very well done.

So far one of the things I more or less sorted out are the tyres, which in the original game are entirely wrong and are probably the main culprit for making the cars so tame.
For my private use only, of course, I borrowed the tyres from the rfactor HSO 1972 F5000 mod and F1 Seven became an entirely different game, very much more GPL-wise and akin to vids from those times. In two words: a powerslide party.

I'm also looking to get some other things right, in particular 'mass', which I'm not sure the modders got very right. The cars' weight in those times is usually between 550 and 590 and I see 'mass' values varying wildly from low to high 600's.

So yeah, if you have any further feedback on this mod's physics it will be most appreciated!

Don't know if your aware of the player PLR file.
Alter the Half rate for more realistic physics.
Also some other stuff you can do.
Just alter with notepad.
If it won't save directly in the directory after altering. Copy the plr file to desktop. Alter there then copy and paste into player file over original plr file. Don't forget to keep a copy too of original plr file.

I actually knew about it (as I had made that tweak to get a better feel with 99-02 cars) but completely forgot to add it to the F1 Seven Mods. So thanks for refreshing my memory It does get a bit better, but it's definitely a question of tyres; plus the default setup is very understeery.

For those potentially interested: the first releases of F1 Seven consisted of 75, 74 & 73: all made by the same modding team, and the feeling is usually good.
Then there was 72,71,70, but these were made by a different modding team, which carried on with the unfinished material left by the original modders. The physics are basically copy-pasted from the previous releases, and often with some incongruent values. And after looking at the files I found out that the tyres were not made from scratch (like in 73-5) but taken from some Rfactor mod ( and definitely not a good one).

So either I'll use the 73-5 tyres but modified according to 70-2 evolving dimensions; or further tweak those from the HSO mod. ANy of these solutions, though, is a lot of fun as the cars are more challenging and loose.

There are two errors:
The 1971 mod (as 1973-74-75) was also made by the original authors (Team Crew).
Then, I participated in the 1970 and 1972 production (TNT Team) and I do not think we took anything from rfactor, considering that for that game have never released nothing of that years.
And the few mod that you find are all conversions of F1 Challenge's mods.

and since a bit of race simulation history is never too much, here are release dates ....
